Language understanding systems allow users to communicate with a computer or network and accomplish various tasks by providing natural language input. Such systems typically analyze the elements of the received by natural language input (e.g., text or speech) to determine a user's intent, determine the correct task to accomplish that intent, and to gather the necessary parameters to fulfill that task. Tasks may include activating and providing information to an application, performing a query, ordering goods or services from a provider, or scheduling events on a calendar. Typically, each third-party application designer who wishes to interface with language understanding systems must write an application interface to handle all aspects of the user's communication. Frequently, however, this results in multiple third parties duplicating significant portions of these interfaces when solving for similar circumstances. It is with respect to these and other general considerations that aspects of the present disclosure were developed. Also, while specific problems and circumstances are discussed herein, it should be understood that the inventions discussed herein are not limited to solving those only those problems or working in those circumstances.
